Difference in Boeing's EBIT between 10k and Aswath Damodaran's DCF evaluation sheet

I am using the Aswath Damodaran sheet on valuation.

I am specifically using fcffsimpleginzuCorona. I am also following his guide for it on Youtube

He is using Boeing as an example. If you look at the sheet, he entered Operating income/EBIT as -2102 for 2019 and 11 843 for 2018

If you actually look at the 10K, those numbers are -1,975 for 2019 and 11,987 for 2018

I like to understand why is the difference?
